ABSTRACT
If one looks at Marxism and Keynesianism from an ideological and political perspective, the difficulty in finding a relationship between them is evident. Marxist and Keynesian economics appear to be far apart, but there exist important points of contact between the two approaches to economic problems. Joan Robinson, one of the most prominent Keynesian economists, has showed a constant interest in Marx's economics and its relationship to the Keynesian approach. In 1933, Keynes drafted several chapters of The General Theory where the critique of the classical doctrine and Say's Law is based on the distinction between a co-operative economy and an entrepreneur economy, that is, the capitalist economy in which "we actually live". Banks play a crucial role in the process of growth of the economy. Banks are capitalist firms as well; they may have a high "liquidity preference" if they expect that lending is not profitable enough or too risky.
